4 Signs You Need Leak Detection

1. The musky smell of mold or mildew – If you’re noticing that distinguishable musky smell of mold or mildew, but you can’t find it, call in our expert leak detection specialists. A small mold problem can turn ugly quickly.

2. Cracks in your wall paint – Not all water leaks are going to be strong enough to cause a noticeable water stain, but they might have an affect on your wall’s paint. Make sure to note any new cracks to our leak detection specialists upon their arrival.

3. An unusually high water bill – The worst way to find out you have a leak is through an astronomically high water bill. Call in our Ontario leak detection experts and we’ll get to the bottom of your costly leak.

4. The water meter test – If you ever do suspect that you may have a leak, testing to see is easy. Turn off all your water and head to your water meter. If the dial is moving or not at 0 then you have a leak.

Thousands of Happy Customers

Was very happy with the quick response to my call for help. It was a very good experience even though it was a stressful situation. They worked with me and were empathetic to my problem and my limitations. They were very thorough in explaining the situation and what needed to be done, explaining and showing me the problem. Once it was decided what I had to do they were quick to get to work and completed the job in a very timely manner. All in all it was a stressful but good experience

– Susan C.

All Pro was awesome we called and they came the same day when our shower drain was leaking into our downstairs ceiling…..the service person was so nice and was very fast and very professional. The price was very reasonable and affordable. They did an outstanding job and we would recommend this company for all your servicing needs. This is the second time using this company, the first was for our water heater and they replaced it fast and very affordable the same day. They came at around 5 and was here until around 9 fixing not only our leaking shower drain but our water pressure value needed to be replaced. They did both and I do not think we would have gotten a better deal or a nicer person to come and do the repairs. All Pro is definitely the people we will be calling for all our plumbing, heating and air conditioning needs from now on.

– Pamela M.

They came to our rescue on January 8, 2018. we had a clogged toilet that overflowed all the way to the downstairs bathroom it was a horrific scene that day. That is when we decided to call All Pro Plumbing. Talked to a nice lady on the phone gave her our info and told us would call back to ensure us someone would come out to help. Within minutes gave us a response time and told us someone will be there within the hour. Sure enough that is when they showed up and quickly diagnosed the problem, went to work, and unclogged whatever was in there that needed to be unclogged. They were efficient, respectful, and professional. They also checkout out other things to make sure that toilet was working fine before they left. Great customer service!

– Vincent M.

Gary was absolutely amazing today. He was friendly, knowledgeable! It seemed a little pricey but our problem needed to be addressed immediately. Great customer service. I would definitely recommend!

– Danielle O.

I would recommend ALL PRO Plumbing to anyone that is looking for good professional service. They installed a sink and garbage disposal for me and did a great job. Their response time is quick. Always either the same day, or the next day

Handling Water Leaks

Whether the leak in your plumbing is minor or major, it should be taken care of as soon as possible by a reliable plumber to prevent damage. Even if you haven’t directly seen the leak, contact our expert San Bernardino County plumbers if you suspect a leak is hiding within your walls, floor, or ceiling.

Common Causes Of Water Leaks Include:

  • Clogged drains and toilets: Without even realizing, you may have a clog in your drains or toilet that has caused a leak.
  • Aging or old pipes: The older your pipes, the weaker they are. Worn out pipes can become prone to leaks.
  • Intrusive tree roots: The roots of trees in your yard may wrap around your pipes, causing leaks.

No matter how big or small your leak is, we can be there 24/7 to assist you. We work tirelessly to ensure that the plumbing in your home is in perfect working order!

How To Prevent Water Leaks

Sometimes, it is obvious when you have a leak. You can physically see moisture on pipes or pooling water around your plumbing fixtures. Sometimes though, you may suspect a leak, but be unsure of where it is located or how serious it is. It’s situations like this where you need to call in Ontario leak detection professionals who have specialized equipment to help you locate the problem and fix it immediately, keeping expensive water damage at bay. While our plumbers are here to help in the event that you experience a leak, there are a few things you can do that can help prevent this.

Preventative Maintenance Steps You Can Take

  • Check faucets and under sinks for drips and corrosion on pipes.
  • Remove faucet aerators regularly to clean them from debris.
  • Avoid putting grease and other food matter down your pipes, which can create clogs, putting pressure on your pipes.
  • Drain water from your hot water tank every few months to remove sediment.
  • It would be wise to upgrade to PVC piping, which is more durable and less likely to spring a leak.

Resolving Dangerous Slab Leaks

A slab leak is a water leak that occurs beneath the concrete slab supporting the foundation of your house. Slab leaks affect the soil under the concrete, ultimately compromising the structural integrity of your home’s foundation. If water reaches your home’s structural components, they can warp, bend or even break. Additionally, if a slow trickle turns into a flood, your belongings can get damaged or possibly even destroyed. Failure to address a slab leak can result in extreme damage, requiring extensive and costly repairs.

To determine whether your home has a slab leak, look for these warning signs:

  • The sound of water underneath your floor
  • Cool spots on your home’s concrete slab
  • Unexpected increases in your water bill
  • Water pooling around your home’s foundation
  • The formation of cracks in your concrete slab
  • Water stains on the floor of your home
  • Mold growth, which is a serious health threat
  • Lowered water pressure
  • A musty odor coming from your home

If you notice any of these, call our Ontario leak detection team of experts for a fast assessment and affordable repair.
